What is competition in ecology?

Back

Competition occurs when two or more species vie for the same resources (such as food, space, or light) in an ecosystem, which can limit their growth and survival.

Explain mutualism.

Back

Mutualism is a type of interaction where both species involved benefit from the relationship.

Front

What is parasitism?

Back

Parasitism is a relationship where one organism (the parasite) benefits at the expense of another organism (the host), often causing harm to the host.

How do parasites and predators maintain ecosystem stability?

Back

Parasites and predators help maintain ecosystem stability by decreasing the population of certain organisms, preventing any one species from overpopulating.

What is the difference between mutualism and commensalism?

Back

In mutualism, both species benefit, while in commensalism, one species benefits and the other is unaffected.

Front

Give an example of competition in an ecosystem.

Back

An example of competition is when sloths and monkeys compete for limited space and resources in a tropical habitat.

What is the impact of deforestation on species interactions?

Back

Deforestation can lead to increased competition among species for limited resources, as their habitats are reduced.
